You can customize the content and order of commands in the main shortcut menu (the one that opens when you right click in the editor window). The choice of commands is the same as those available for the toolbar.
Just put a check mark in front of the commands you would like to show in the shortcut menu. You can drag-and-drop to reorder commands. Use the list's shortcut menu to sort items or group those you selected, or to check/uncheck all items.
